The famed Buderus GB142 was the flagship in the mid 0s to the mid teens. They are slowly fading away. Here’s the basic gist:
Option A- keep costs down and slide in the new boiler
Option B- spend a bit more and replace all the goodies
This job is option A. But please notice, this boiler does not have the “chopped in” look. I realize most homeowners cannot tell, but I can and the heating guys can.
Whoever installed the Buderus installed the behemoth. The GB142 was 214,000 BTU. We stuck a Viessmann 150,000 BTU onto the wall. It always fascinates me. Why so many heating guys install huge stuff. Not good for “cycling”. Low mass boilers don’t like it. Had it not been for the huge cast-iron radiators, the BTU would’ve been even lower.
